Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat device.

[0002]

2. Description of the Related Art In many cases, a vehicle seat is slidable in the front-rear direction. In particular, a rear seat positioned behind a front-row seat constituting a driver's seat and a passenger seat is largely moved in the front-rear direction. May be slidable.

[0003] In some cases, a plurality of front and rear sheets are guided in the front-rear direction by the same guide rail using a long guide rail extending in the front-rear direction (for example, Japanese Utility Model Application Laid-Open No. 61-8 / 1986).
No. 0132). The above publication also discloses that a plurality of front and rear sheets can be double-faulted on the same (common) guide rail.

[0004]

When a plurality of front and rear sheets are guided by the same guide rail, each of the front and rear sheets can be independently slidably adjusted. Each will have a slider. In this case, when each sheet is double-faulted, the minimum distance between the double-faulted sheets is when the front and rear sliders are closest to each other, but there is a limit to the proximity between the sliders (the same guide rail). Therefore, since the plurality of sliders are guided, the state in which the sliders are in contact in the front-rear direction is closest to each other), and there is a limit in reducing the distance between the double-faulted sheets in the front-rear direction. This imposes a limit on the increase in the longitudinal length of the passenger compartment obtained by double-faulting.

On the other hand, the floor panel to which the guide rail is attached is provided with irregularities from various viewpoints.
For example, in order to expand the foot space downward, a large recess may be formed downward to form a recess having a considerably large area. If the guide rail is long in the front-rear direction, a situation arises in which the guide rail must be disposed across a large recess. Arranging the guide rail across the concave portion is advantageous in that the guide rail is easily bent downward at the concave portion, and the seat is firmly supported by the guide rail, and the seat is guided by the guide rail. This is not preferable in that a smooth slide in the front-rear direction is ensured.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a first object of the present invention is to make it possible to enlarge the cabin more in the front-rear direction when a plurality of front and rear seats are respectively double-faulted. To provide a seat device for a vehicle. A second object of the present invention is to provide a seat device for a vehicle in which a guide rail is prevented from being greatly bent at the concave portion even when the guide rail is disposed across a large concave portion provided on the floor panel. To provide.

According to the first aspect, when a plurality of front and rear sheets are double-faulted, a plurality of sheets are double-faulted on one slider. The length in the front-rear direction of the plurality of seats in the double-faulted state is sufficiently shorter than before, and the distribution chamber can be greatly expanded in the front-rear direction.

According to the second aspect, by utilizing the removal of the sheet from the slider, the removed sheet can be easily engaged with another slider for a double fault. According to the third aspect, the plurality of seats that have been double-faulted can be grouped forward in the vehicle compartment, and the luggage compartment formed behind the seat that has been double-faulted can be extended in the front-rear direction. According to the fourth aspect, the sheet can be stably supported in the front-rear direction, which is the sliding direction, by engaging the sheet with the slider at two front and rear positions. In addition, by making the length between the front and rear engagement portions of the front slider longer than the front-rear thickness of the rear sheet when double-faulted, the double-faulted rear sheet can be stably and reliably placed on the front slider. Can be supported.

According to the fifth aspect, the sheet can be stably supported in the front-rear direction, which is the sliding direction, by engaging the sheet with the slider at two front and rear positions. Further, the rear engaging portion of the front slider can be effectively used as a swing center when the rear sheet is double-faulted on the front slider. According to the sixth aspect, it is possible to prevent a situation in which each of the front and rear double-faulted sheets is inadvertently moved in the front-rear direction only by fixing one double-faulted sheet.

According to the seventh aspect, since the guide rail is supported at the concave portion via the leg portion, a situation in which the guide rail is greatly bent at the concave portion is prevented, and the seat is made firm. It is possible to obtain the support and the smooth sliding of the seat. According to claim 8, the leg portion is formed as a shape along the side cross-sectional shape of the concave portion, that is, the leg portion exists over the entire length in the front-rear direction of the concave portion, and the effect corresponding to claim 7 is more sufficiently achieved. It is preferable to exert the effect on .

According to the ninth aspect, the rigidity of the floor panel can be sufficiently increased by the tunnel portion and the pair of left and right concave portions. According to the tenth aspect, the concave portion can be effectively used for storing a storage space or expanding the space below the occupant's feet.
